AUTOMATICALLY-ADJUSTABLE BASE.

Application. filed February 20, 1923. Serial No. 620,145.

This invention is. especially adapted for use as a base for supportingpaint buckets,

and the like, to keep thesame level on i11 clined surfacessuch asv roofsand the like and on convex and concave surfacessuch for instance as onthe outside or inside "round ing surface of a large pipe, drumouglobe.

An object of this invention ,,is to facilitate the use of paintbucketsandother open top containers on roofsand other non-levelsurfaces; and the invention is broadly new,

basic'and pioneer in that I provide avessel holder with a looselyjointed toggle like supthe same is supported by hand independently ofany other support, and adapted to conform by ts own weight to suchsurface as it may be lowered onto, and to retain the position atwhichthe vessel holder is brought to rest, irrespective as to whether itbethe side or the peak of a roof or in avalley or gutter; and which willretain the holder in the position it is in when the parts come to rest,and hold such pail or other receptacle against accidental displacement.or tilting on the base, and which is constructed to prevent any slippingof saldb'asje on the surface on which it may be placeda Another objectis to provide forinclined surfaces, a base for pails and the like whichmay quickly and easily be moved from place to place as the workprogresses, thus to avoid the necessity of fixing a bracket, aframework, or cleats" to or on the roof at each placing of said pail.

Another object is to provide for pails and other receptacles, a basetowhich the receptacle may quickly" and easily be attached and as quicklyand easily detachedpwhen de' sired.

the pail and base may be lifted bythe hail of the pail and carried fromplace to place without disengaging the pail from the base.

An advantage is that the base is antislipping so that its use enablesthe work men to leave the surface from which 1t has been removed, freefrom nail holes.

The invention is adapted to be used by other mechanics and builderS;,,being suitable for use by shinglers to hold their shingles or to sit on,or by tinnersto supporttheir fire pots; and by brick layers to holdbrick or An object is to make provision whereby casion.

FFIE.

The invention includes aseat supporting jointed frame comprising twoswinging stay legs pivoted on axes that are in fixed relation to theseat and two tiele 's that are pivotally connected together by a lostinotion connection, and respectively pivoted .to the stay legs, the ties'being adapted to.

linear adjustment to hold the stays rigidly aslant at reversed anglesrelative to the seat; and to each other and also adapted to augularadjustment tohold the stays rigidly extended toward the oppositeendsof'one or the other ofthe ties.

Fig. 8 is an elevation of another form and shows how the adjustablesupporting limbs drop down when the device is carried by the seat orplatform.

Theplatform orrigid seat l is adapted to hold a pail or receptacle 2 andis pivoted to a jointed frame that is adjustable to various surfaces,such as,horizontal, concave, convex or slanting, while the seat 1 ishorizontal, and that will" support the seat and its load when the frameis thus afdjusted.

b'ects advanta es and features of The accompanying drawing illustratesthe" pail being brokencomprising a pair of braces 4,5 and a pair of ties6, 7. The braces are pivoted at one end to said ears; the braces 4, 4being pivot ed to the mm 4, 4 and the braces 5, 5 being pivoted to theears 5,5." The limbs 6, 7, ofthe ties are each approximately equal inlength to the spacebetweeii centers of their pivots 8, 9 that connectthem with the ears 4', 5 that are secured to the platform 1 or seatbythe rigid strips 10 and 11 so that the seat is 'rigidand the pivotalaxes at 4 and 5" are held' in parallelism.

The long limbsfi, 7 are connected together by 'a lost motion pivotalconnection at 12, and are "also pivoted at 13,1410 the short limbs 4, 5and to therigid 'base'bars 15,

16 which are'tiirned up at the ends to form ears which base bars andtheir pivotal axes 13,: 14 'a'iidthe pivotal avis 12 are held inparallelism with each, other.

Stops 17,18 are provided; on the limbs 4, 5 to bear against the limbs'6,7 for the purpose ofinsuring the toggles against collapse. Spurs IQ-areprovided onthe underside of the seat to engage the roof'in case the baseis placed on theinclinled surface of such roof. Said spurs are"preferably formed of the down-turned ends ofa strip or bar'2Qof metal,applied directly beneath the jstrip 11; said ,endsbeing pointed to formthe'spurs 19. l Rivets 21are used to attach both the strips 11 and 20 tothe seat 1.. Said spurs 19 m of a length to merely catchjin'to the roofsnfiiciently to retain the base on the slanting 'surface of the.roo'flas shown in Fig. 5 when' si eh roof is composed of shingles orany penetrable material not likelyto be injured by the sp'urs. In thisposition the stops 17. will engage against the stay legs 6 to rigidlysupport, the outer end of the platform 1.

Provision is made to prevent slipping in cases where the use of spurs miht prove inju'riousas on roofing or the like, such provision being 'astrip 22 of rubber attached. to the underside of'theseat 1"at theedgeopposite to that near which, the spurs 19 are placed; said strip 22extending flush with or 'a trifle beyondjthe edge 23 of. the platform.Fig. 8 shows in dot and dash lines'the positionof the base in such engagement Thusifthe base may be turned at pleasiire to engage, at eitheredge with the roofa'spccasion requires. It is seen that in abalanced.:position as shown in Figs.

- 3 or 6th efretain ersf19 and, 22are not .re

quired and are out of the'wayj 2. Means for clamping a pail orreceptacle 2 on the platform 1 are shown in Figs. 1 to 7 inclusive. Theclamping means may be in the form of curved jaws 24 adapted for use witha circular pail or with straight and parallel jaws 24 as shown in Fig. 7to be u'se'chwith a rectangular receptacle.

Said jaws 0r clamps 24, 24 are operated as shown in Fig. 2 by means ofslides 25, links 26, lever 27, spring 28 and pull rod 29. The slides 25are attached at one end to the clamps 24 and operate in slidcways 30while the other ends of the slides 25 are pivotally connected by thelinks 26 to the lever 27; said lever being pivoted at 31 to the platform1 and operated by pull rod 29 against the tension of the spring 28 whichconnects the outer end of the lever 27 with the platform 1.

The clamping means may be omitted if desired as shown in Fig. 8,

The parts of the frame are arranged in pairs, as the stay legs 4, 4 and5, 5; the tie limbs 6, 6 and 7, 7; and the base bars 15, 16 are pivotedtogether by the limbs 6, 7 and pairs of pivots12, 13, 14 to constitute atogformed by the limbs 6, 7 being adapted to linear adjustment as shownin Fig. 3 when the pivots 12, 13 and 14 are in a common plane to holdthe stays rigidly aslant at 'reversed angles relative to the seat and toeach other; and are also adapted to angular adjustment to hold the stays4, 5 rigidly 0X- tended respectivelytoward opposite ends of one or theother of the ties. The slols12 allow the lost motion joint of the tiesto pass the alined position shown in Fig. 3 so as to conform to the combof a roof as shown in Fig. 6, or to the side of a roof as in Fig.

The jaws 24 are shown spaced apart from the seat 23 suiiieiently toallow the bottom flange 32 of the pail to be inserted between the jaws24 and the seat as indicated in Figs. 3, 4 and 5, so that when the pailis lifted by the bail 33 the seat and the jointed frame will be liftedalso.

The slots 12' allow the tie limbs 6, 7 to pass the plane in which thepivots 13, 14 lie so that the frame may be brought into the differentpositions required for supporting the seat in a level position abovevarious surfaces.

It is thus seen that the seat is provided with a swinging jointed frameadaptedto hang from the seat whenever the seat is uplifted and that isautomatically adjustable to level, to slanting, to convex, and toconcave surfaces, alternatively according to the relative positionsimposed upon such frame by gravity assisted by pressure of the hand uponthe seat when the toggle joint frame is at rest on the surface to which.it is to corn form.

I claim:

1. A support comprising a seat, a toggle frame pivotally connected tosaid seat, said frame comprising pairs or" braces pivotally connected tothe opposite endso'f said seat, pairs of ties pivoted at one end to saidbraces and pivoted together at their other end with lost motionconnections.

2. A support having a rigid seat and a jointed frame pivoted thereto onaxes in fixed relation to said seat; said tramecomprising pairs oi.braces pivoted on said axes; pairs of ties ot a length approximatelyequal. to the space between said axes; each pair of ties beingpivotedtogether at one end and pivotally connected at their other endsto said braces.

3. The combination with a rigid seat of pairs of base bars, bracespivotally connecting one pair of the base bars to the seat at one sideof the center thereof; braces pivotally connecting the other pair ofbase bars to the seat at the other side of said center; and pairs ofties comprising limbs pivotally connecting the base bars together tohold the same in parallelism with each other.

4-. A support comprising a seat, a toggle tram-e pivotally connected tosaid seat, said frame comprising pairs of braces pivotally connected tothe opposite sides of said seat, pairs of ties pivoted at one end tosaid braces and pivoted together at their other end with lost motionconnections, and rigid base bars extending between said toggle framesand connected to the pivots between said ties and braces.

5. The combination with a seat, of a oint ed trame comprising base barsconnected together by pairs of ties pivoted to said bars and to eachother, and pairs of braces connected to said seat and said ties andadapted to swing under the seat at one edge of said seat and to a stopat the other edge of the seat so as to form a support for the seat on aslanting surface; and antislipping .means adapted to engage the surface,said means be ing secured to the seat.

(j. The combination with a seat provided with a stop at one edge; of ajointed frame con'lprising base bars connected together by pairs of tiespivoted to said bars and to each other; and pairs of braces connected tosaid and'ties'and adapted to swing under the seatat one edge of saidseat and to the stop at the other edge of the seat so as to form asupport for the seat on a slanting surface; and antislipping means fixedto the seat on the side of the seat opposite the stop.

7. A seat having downwardly extending ears at opposite edges anddownwardly extending friction devices at opposite edges; a jointedsupport comprising pairs of ties and braces pivotally connectedtogether'and to said bars to form a frame; and stops on said braces torest .on the ties to prevent collapse of the frame.
